Abstract: An auto-injection system provides high throughput screening of fluidic samples. A sample injection valve has a first position which applies a reduced pressure to a sample sipper tube for aspirating a fluidic sample into the sample sipper tube, and a second position which delivers the fluidic sample to a sample supply loop. A column control valve has a first position which delivers the fluidic sample from the sample supply loop to a sample chromatography column, and a second position which reverses direction of fluid flow through the sample chromatography column to deliver the fluidic sample to a sample analyzer. A wash control valve has a first position which supplies a wash buffer solution to the sample chromatography column in a forward fluid flow direction, and a second position which supplies elution solvent to flush the sample supply loop.

Abstract: In accordance with an illustrative embodiment of the invention, a system for obtaining a fluidic sample from a container is presented. The container defines a volume for holding the sample, the volume being closed by a seal. An outer tube has a proximal end and a distal end, the proximal end shaped to permit piercing the seal. An inner tube has an end region axially movable within the outer tube between a piercing position, wherein an end of the inner tube in the end region is retracted from the proximal end of the outer tube, and a transmission position, wherein the end of the inner tube extends axially beyond the proximal end of the outer tube. The outer tube and the inner tube form a tube assembly. At least one of the tube assembly and the container can be moved to cause the outer tube to pierce the seal and, after the seal is pierced, the inner tube can be used in the transmission position to permit fluid transfer with respect to the volume.

Abstract: A system and method high throughput sample preparation and analysis using column chromatography. Each port in a plurality of ports has a port input that interfaces with a first fluid source and a port output. A fluidic circuit is coupled to each port output and to a second fluid source, the fluidic circuit for controlling fluid flow from the plurality of ports and the second fluid source. The fluidic circuit is also coupled to a plurality of chromatography columns. An interface to an analyzer receives output from at least one of the plurality of chromatography columns. The plurality of chromatography columns is moved relative to the analyzer via a translation stage, such that sample output from one of the plurality of chromatography columns can be selectively presented to the analyzer.

Abstract: A system for high throughput sample preparation and analysis. The system includes a chromatography column including an insoluble matrix. A fluidic circuit is capable of passing a fluid over the insoluble matrix in a first direction such that an analyte in the fluid binds to the insoluble matrix, and back-eluting an elution fluid over the insoluble matrix in a second direction opposite the first direction to output a sample that includes the analyte. A controller controls the fluidic circuit to periodically perform the steps of passing the fluid over the insoluble matrix and back-eluting the elution fluid over the insoluble matrix to output a plurality of samples at a periodic rate.

Abstract: A system and method for high throughput screening of fluid samples. A reduced pressure is applied, via an injection valve, to a sample aspiration tube. A first fluid and a second fluid are alternatively aspirated, via the sample aspiration tube, the first fluid for filling a sample loop with samples, the second fluid for flushing the sample aspiration tube. Excess fluid aspirated from the first fluid source and all fluid aspirated from the second fluid source is captured in an inline trap.
